This change makes it possible to pass '-Ddbus-group=<group>' to limit
the access to the ratbagd D-Bus service. The default remains to allow
everyone access to the service.
This allows integrators to choose more conservative security settings
e.g. only allowing users in the 'games' group to talk to the ratbagd
daemon.
When developing with ratbagd, we need to test against master, not
the system-wide installed daemon.
Allow to name space ratbagd with the creation of a new (not installed)
rabtagd.devel daemon, that is tagged with the git sha of the ratbagd
folder.
Handle this namespace in ratbagctl by looking at an environment variable
RATBAGCTL_DEVEL.
Then provide a python script that launches both rabtagd.devel and
ratbagctl with the correct environment variable set so that they can
talk to each other.
Note that we blindly overwrite the dbus .conf file as nobody else than
developers should have one.
Note: the tagging of ratbagd.devel (like the meson bit) won't run unless
a rebuild is triggered. So we don't necessarily always get the right git
tag. However, touching ratbagctl.in triggers a rebuild, so we should be
OK-ish.
